7 Chapter 1, Instrument Safety and Certifications The ALTAIR Pro Single Gas Detector is: For use by trained, qualified personnel Designed to be used when performing a hazard assessment to determine the appropriate gas monitoring needed for a workplace. To be used when performing a hazard assessment to: Assess potential worker exposure to Specific toxic gases for which a sensor is installed Oxygen-deficient or oxygen-rich atmospheres for oxygen versions only NOTE: Although the ALTAIR Pro O 2 unit will detect up to 25% oxygen, all ALTAIR Pro versions are not certified or classified for use in atmospheres containing more than 21.0% oxygen. " WARNING Read and follow all instructions carefully. Do not use this detector to sample the instrument s specified gas in gases other than air. Perform an alarm function check and a bump test before each day s use. If the instrument fails either check, the instrument must be taken out of service. Recheck response and alarm function if the instrument is subjected to physical shock. Do not alter this instrument or make repairs beyond those specified in this manual. Only MSA-authorized personnel may repair this unit; otherwise, damage may result. This unit contains a lithium battery; dispose of according to local regulations. Wait for an accurate reading; response times vary, based on the gas being detected. Use only to detect a gas for which a sensor is installed. Do not block sensor. Leave area immediately if a gas alarm condition is reached. 1-1

8 Do not use pressurized air to clean the sensor or alarm holes. All instrument readings and information must be interpreted by someone trained and qualified in interpreting instrument readings in relation to the specific environment, industrial practice and exposure limitations. ALTAIR Pro Detector s gas sensors may have a crosssensitivity response to common interference gases other than the gas it is designed to detect. In some cases, this cross-sensitivity may be positive, producing a reading higher than actual. In other cases, it may be negative, giving lower readings or even negative. Contact MSA for further details if crosssensitivity may be an issue. Special requirements for ALTAIR PRO O 2 -R Remote Oxygen Detector: Operate this instrument only in ambient temperatures ranging from 0ºC to 40ºC (32ºF to 104ºF). If the instrument is taken into an environment where the ambient temperature is 15ºC (59ºF) or more, higher or lower, than its previous location, do not use the instrument for a period of 40 minutes to allow the sensor to adjust to the new conditions. After this 40-minute period, perform a Fresh Air Set-up (FAS) to re-zero the sensor. Perform the FAS in fresh air only. Quick changes in barometric pressure result in an offset in the sensor reading for a few minutes. If this occurs, do not use the instrument for a period of five minutes; then, perform a Fresh Air Set-up (FAS) to re-zero the sensor. Perform the FAS in fresh air only. Conditions for Safe Use: When it is necessary to replace the battery, use only a Lithium battery listed in TABLE 6-2. Use only the specified MSA cable connecting the remote Oxygen sensor. The maximum length of the remote sensor connecting cable must not exceed 3.3 meters (10 feet). INCORRECT USE OR FAILURE TO FOLLOW THIS WARNING CAN RESULT IN SERIOUS PERSONAL INJURY OR DEATH. 1-2

" WARNING If a toxic or oxygen gas alarm condition is reached while using the instrument as a personal or area monitor, leave the area immediately: the ambient condition has reached a preset alarm level. Failure to follow this warning will cause overexposure to toxic gases, which can result in serious personal injury or death. Oxygen Measurements The ALTAIR Pro Detector can be purchased to measure the concentration of oxygen in an atmosphere. The value displayed is percent by volume of oxygen in the atmosphere. High and Low alarm setpoints can be configured to alarm in any combination of oxygen: enrichment (greater than 20.8%) or 2-11

21 depletion (less than 20.8%). When an alarm setpoint is reached, the: Audible alarm sounds Alarm lights flash Vibrator activates Type of alarm displays by alternately flashing the ALARM icon and the LO or HIGH icon, depending on how the Low and High alarms were set. Low Alarm indicates: the lower %O 2 level of the two alarm settings a more urgent condition and the faster alarm sequence will be indicated "LO" "ALARM" displays. NOTE: The LOW alarm (lower of the two %O 2 alarm settings) is latching and will not reset when O 2 concentration rises above the LOW setpoint. To reset alarm push the TEST button False oxygen alarms can occur due to barometric pressure (altitude) changes or extreme changes in ambient temperature. It is recommended that an oxygen calibration be performed at the temperature and pressure of use. Be sure that the instrument is in known fresh air before performing a calibration. Special requirements for ALTAIR PRO O 2 -R Remote Oxygen Detector: Operate this instrument only in ambient temperatures ranging from 0ºC to 40ºC (32ºF to 104ºF).
